Important! For more detailed information on the capabilities of these circuit packs, see Circuit packs in Chapter 4, Product description. For technical specifications, see Chapter 10, Technical specifications.

System controller - SYSCTL (no network interfaces)

Alcatel-Lucent 1665 DMXtend supports the LNW2 SYSCTL. The SYSCTL provides communication with other circuit packs on the Alcatel-Lucent 1665 DMXtend shelf. The SYSCTL supports all Alcatel-Lucent 1665 DMXtend operations interfaces, including IAO LAN (OSI or TCP/IP), TL1, CIT, office alarms, and miscellaneous discretes. The SYSCTL also supports DCC terminations for each optical line interface.

Network interface circuit packs

This section briefly details the circuit packs currently available to provide or support network interfaces for the Alcatel-Lucent 1665 DMXtend. This includes all of the high-speed circuit packs, housed in the MAIN slots of the Alcatel-Lucent 1665 DMXtend shelf, and used to provide the connection to the core-side of the network.

VLF Main circuit packs (LNW84/LNW141)

Alcatel-Lucent 1665 DMXtend supports the following VLF Main circuit packs, and supports 0x1 port application on these packs:

The VLF circuit packs also enable true 0x1 operation among the tributary slots by supporting independent cross-connections to the ports in slot 1 and slot 2 of the same low-speed group. True 0x1 allows, with some restrictions, different packs within the same function/growth group.

All tributary circuit packs, with the exception of the LNW7, LNW39, LNW111, LNW112, and LNW391 are supported by the VLF circuit packs.

OC-3/12/48/192 network interface (high-speed) circuit packs

Alcatel-Lucent 1665 DMXtend supports the following OC-3/12/48/192 network interface cards:

Tributary interface circuit packs

This section briefly details the circuit packs currently available to provide or support tributary interfaces for the Alcatel-Lucent 1665 DMXtend. This includes all of the low-speed circuit packs and housed in the Function/Growth slots of the Alcatel-Lucent 1665 DMXtend shelf

Optical, tributary interface circuit packs

Note: When the shelf is equipped with non-VLF mains, the low-speed circuit packs support the VT mapping as specified below. When the shelf is equipped with VLF mains, all VT connections are performed in the Mains.

Alcatel-Lucent 1665 DMXtend supports the following optical, tributary interface circuit packs:

WDMX, tributary interface circuit packs

WDMX is the name of a family of features that adds metro WDM capabilities to the Alcatel-Lucent 1665 DMXtend product line. WDMX is the integration of WDM functions directly on the Alcatel-Lucent 1665 DMXtend shelf platform. It adds ITU-T Optical Transport Network (OTN) layered structure for WDM within the shelf footprint.

Alcatel-Lucent 1665 DMXtend provides WDMX capabilities with the following circuit packs:

The LNW705 and LNW785 must be installed in a shelf with an LNW2 and at least one Main pack. VLF and non-VLF Mains support the WDM packs.

Electrical, tributary interface circuit packs

Alcatel-Lucent 1665 DMXtend supports the following electrical, tributary interface circuit packs:

Ethernet interface circuit packs

Alcatel-Lucent 1665 DMXtend supports the following Ethernet interface circuit packs:

Other hardware features

Alcatel-Lucent 1665 DMXtend also supports the following hardware:

Pluggable transmission modules (PTMs)

PTM optics are pluggable optics. Circuit packs using pluggable optics do not come equipped with optics; you can order only the number and type of optics required at the time of installation. Additional optics can then be ordered as new services are required which makes Alcatel-Lucent 1665 DMXtend interface density scalable to meet the unique needs of each customer. The PTM optics also allow for some versatility in the span lengths and rates that can be covered by the same pack.

PTMs are either SFPs or XFPs. OC-3, OC-12, OC-48, Fast Ethernet, and Gigabit Ethernet ports use optical SFPs. OC-192 port use optical XFPs. Electrical SFPs are also available for Fast Ethernet and Gigabit Ethernet ports The LNW705 (10G Muxponder) packs use SFPs on the 8 client ports and an XFP on the OTU2 port.

The LNW63/64/87/170 packs support dual-function electrical SFPs that are provisionable for 100 or 1000 Mbps (electrical FE or GbE) traffic. They conform to the IEEE802.3 standards for 100BASE-T and 1000BASE-T in the respective settings (IEEE802.3z and IEE802.3ab). Connectivity is provided for an RJ-45 Cat 5 cable and the SFP has a maximum span length of 100 meters.

External optical amplifiers

For OC-48/192 spans of up to 140 km, Alcatel-Lucent offers external optical amplifiers. The external optical amplifier is a stand-alone shelf and can be used with both OC-48 and OC-192 optics.

External optical amplifiers consist of one booster and one pre-amplifier part. The booster part is connected via a Dispersion Compensation Module (DCM) to the transmit interface of the respective OC-192 or OC-48 port unit. The pre-amplifier part is connected by means of a DCM to the receive interface of the associated port unit.

Passive optics units (POUs)

The Alcatel-Lucent Passive Optics Units (POUs) are a lower-cost solution to using DWDM for transmitting large amounts of traffic on one fiber. This module fits into a bay frame, but reduces the number of Alcatel-Lucent 1665 DMXtend shelves in a bay to three. The box does not require any electrical powering.

POU shelves are available to support the following applications:

Electrical continuity test tool (LNW94)

Alcatel-Lucent 1665 DMXtend supports a circuit pack designed to aid technicians in the installation and maintenance of Electrical interfaces and cables. The Electrical Continuity Test Tool (LNW94) can be placed in D1, D2, G1, G2 on the Alcatel-Lucent 1665 DMXtend shelf. It is used to test the cables which will be connected to DS1, DS3, or Ethernet electrical interfaces. LNW94 tests the integrity of electrical cables to both identify where trouble exists and which cables or DSX panels are faulty prior to installation and turn up.

In-service electric continuity test tool (LNW93)

The In-service Electrical Continuity Test Tool (LNW93) test circuit pack is used for upgrades in the Alcatel-Lucent 1665 DMXtend shelf. An in-service shelf might have a function unit with low capacity DS1 (LNW7) or DS3 (LNW16) packs. When these packs are upgraded with higher capacity packs (DS1, LNW8, DS3, LNW19B), as part of the upgrade procedure, new DS1 or DS3 connectorized cables are added to the DSX cross-connect frames and to the Alcatel-Lucent 1665 DMXtend shelf. The LNW93 pack is used to test out the new wiring without disrupting traffic on the in-service pack.

The LNW93 is very similar to the LNW94 test tool except that it has no backplane connectors for DS1 ports #1–28 or for DS3 ports #1–12. When the LNW93 is plugged in, it makes no contact with the wires on the backplane for those lower ports. Since there is no physical connection, the LNW93 does not interfere with the service of the pack in the other slot of the function unit. The LNW93 tests the integrity of electrical cables to both identify where trouble exists and which cables or DSX panels are faulty prior to installation and turn up of a high density DS1 or DS3 circuit pack.

Removable center-divider

Alcatel-Lucent 1665 DMXtend provides a removable center divider between M1/2 and A1/B1/A2/B2. When the center divider is removed the shelf supports the full-height LNW84 and LNW141 circuit packs. This shelf contains all the capabilities of the standard Alcatel-Lucent 1665 DMXtend shelf, it simply allows the option to remove the center divider in order to support these full-width, high-speed packs in the MAIN slots.

Blank circuit packs

Alcatel-Lucent 1665 DMXtend provides blank cards to be used as fillers in unpopulated slots of the shelf. These fillers help to ensure proper air flow, cooling and EMC safety.

Some blanks can be detected and reported.

Alcatel-Lucent 1665 DMXtend supports three detectable blank circuit packs: LNW95 in an unequipped M2, LNW96 in and unequipped A1/B1 slot, and LNW98 in unequipped Function D and Growth slots.

The WaveStar® CIT reports the presence of a detectable blank in a slot by displaying a blank faceplate graphic instead of an empty slot graphic. No alarms are associated with the insertion or removal of the detectable blank.
